I am running Firefox 61.01 on a Mac OSX 10.9.5. I am getting error messages and insecure site messages for outlook, You Tube, my banks, PayPal, Amazon... sites that are displaying fine on Google and Safari.

On my website, moreover, my Pay Pal buttons have disappeared in Firefox 61.01. 

I have no problem accessing these site using Firefox 48 on my Macs running 10.6.8...

Firefox 61.01 has been very disappointing to say the least.

Hi Pk,


I'm running Malware Bytes for Mac and Kaspersky Internet Security. I've gone back to default settings on Firefox 61.0, so no extensions.

There is security software like Avast/AVG, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate. it is a kaspersky issue as per this forum thread :

But since it is after a update from them you may want to ask your question there.
